Figure 4.2-41 Acquisition of single-phase signal at DPSY01

‡Note: In Figure 4.2-41 two signals can be issued "DPSY01_3PH_STATE" and

"DPSY01_F_QLT_SPP", which are the same as the signals in the Figure 4.2-40.

Event suppression

If the status of a device "chatters" for a short time, the DPSY function will receive iterative

signals from the device. Such iterative signals can cause extra burden for the DPSY function;

hence, event suppression can be required to reduce the additional burden created.

Time.................

Figure 4.2-42 Iterative signals and signals suppressed

Figure 4.2-42 shows that the iterative signals received from the device have been

suppressed by the event suppression function. The suppression commences on receipt of the

seventh signal (at Time 'B'). This is because the function can count the iterative number of

incoming signals. Detection commences at Time 'A', the setting [DPSY-NELD] is provided so

that the suppression commences at Time B. The setting [DPSY-TELD] is pertains to the

Signal acquisition logic in DPSY01
